A study published by F-Secure has revealed a new bug that makes most of the devices, including those equipped with disk encryption, vulnerable to an attack that could steal personal data within minutes.
As he says ZDNet, F-Secure's findings state that modern security measures are enough to prevent theft caused by this new bug.
Attack is a variant of the old cold boot attack, which is a popular technique in the world of hacking. This type of attack resets a computer and then steals the data remaining in the memory RAM.
To steal the data through a cold boot attack, it would require physical access to the computer and specialized hardware. Regular computers are not considered to be the target of such an attack compared to computers that store valuable information such as those owned by government agencies and businesses.
One of the protection measures developed by hardware manufacturers is to replace the RAM content after a computer attack.
F-Secure researchers have found that they can stop the replacement process, making the computer vulnerable.
According to F-Secure's security director, Olle Segerdahl, who is engaged in research, "Although it's not that easy, it's not hard enough to find and exploit this defect, so there's a chance it already exists and some malicious users. "
The researchers said they have warned big companies such as Microsoft, Apple and Intel for their latest findings. Microsoft updated Bitlocker Guidance as an additional security measure while Apple said that all devices using the T2 chip are not vulnerable to these attacks.
